摘要
用差示扫描量热法对均聚聚丙烯(PPH)和添加β成核剂的PPH(β-PPH)的非等温结晶过程进行了研究,并分别用修正Avrami方程的Jeziorny法、Ozawa法及莫志森法处理非等温结晶过程。结果表明:Jeziorny法和莫志森法均能很好描述PPH和β-PPH的非等温结晶动力学;而采用Ozawa法分析PPH和β-PPH的非等温结晶过程效果不理想。
The authors studied the non-isothermal crystallization behavior of homo-polypropylene（PPH） and β-PPH by differential scanning calorimetry（DSC）, and processed the relevant data with Jeziorny, Ozawa method and Mo method of modified Avrami theories. The results show that the Jezinorny and Mo method can appropriately describe the non-isothermal crystallization kinetics of PPH and β-PPH, whereas the Ozawa method fails to do the same ideally.
